The past months have been particularly intense for ODEON. Progress has accelerated across all fronts — from technical development and system design to stakeholder engagement, events, and publications — allowing the project to close the year with a strong sense of achievement and clear momentum for what lies ahead.

A major milestone has been the definition of the functional and technical requirements of the overall ODEON solution, alongside the consolidation of the system architecture. Detailed documentation now describes how Data Space, Security, and Energy Applications components interact, ensuring alignment with the project’s ambitious objectives.

Another key achievement has been the design and initial development of the ODEON Cloud–Edge Data and Intelligence Service Platform. Built around an innovative federated data space and semantic data model, the platform brings intelligence closer to where energy is produced, consumed, and stored. Core components — including the Federated Data Spaces, Cloud–Edge services, and distributed intelligence modules — are already taking shape.

In parallel, ODEON has advanced the first versions of its energy services for DSOs, prosumers, and Local Energy Communities. These modules are now being prepared for large-scale demonstrations planned for early 2026, while efforts to engage citizens and build a critical mass of prosumers continue to intensify.

Throughout 2025, the project held three General Assemblies (in Granada, Amiens, and online), organised a Living Lab in Amiens targeting prosumers, companies, regulators, and other stakeholders, and successfully completed its first project review with the European Commission. Work has also progressed on demo site analysis, demonstration planning, and the first version of the ODEON Exploitation Framework, laying the foundations for future business models and innovation pathways.

ODEON has strengthened its visibility and collaborations through active participation in major events such as Data Week 2025, the BRIDGE General Assembly, EUSEW 2025, SRE 2025, and ENLIT 2025, while reinforcing synergies with initiatives and projects including HEDGE-IoT, ENERTEF, INSIEME, among others.

How do citizens perceive their role in Europe’s energy transition, and what motivates them to become active energy producers? These questions were at the centre of a participatory workshop organised by ODEON in June 2025 in Amiens, France.

Hosted by local demo partner SICAE and designed by Prospex Institute, the session brought together around 15 local prosumers — including farmers and SICAE customers — to share first-hand experiences of producing and consuming renewable energy. The workshop moved beyond traditional consultation, creating an open dialogue on real needs, expectations, and barriers.

Discussions focused on energy sharing, digital tools, and community engagement, highlighting how ODEON’s solutions can better support local energy communities. Participants pointed to high upfront investment costs as a major obstacle, while long-term savings, price stability, and greater control over energy consumption emerged as strong motivators.

The workshop provided valuable insights into the ambitions and concerns of prosumers, reinforcing the importance of citizen-centred solutions in making the energy transition both inclusive and effective.

ODEON has released a new scientific publication advancing the use of Artificial Intelligence in smart energy systems. Authored by partners from the National Technical University of Athens (NTUA), Intracom Telecom, and Barbara IoT, the paper was published in Energy Reports (Elsevier) under the title “Isomorphic Structured Pruning of Temporal CNNs for Scalable NILM on Edge Devices”.

The study introduces Isomorphic Structured Pruning (ISP), an innovative method that significantly optimises deep learning models for Non-Intrusive Load Monitoring (NILM) in resource-constrained edge environments. By intelligently identifying and pruning equivalent network structures, ISP dramatically reduces computational demands while preserving accuracy.

ODEON is advancing the digital energy transition with a cloud–edge data and intelligence platform that brings computing and decision-making closer to where energy is produced, consumed, and stored.

By enabling real-time data capture, local processing, and autonomous control of devices such as smart meters, EV chargers, and home energy gateways, ODEON delivers fast, resilient, and privacy-preserving intelligence for decentralised energy systems. Instead of sending raw data to the cloud, information is processed locally and shared only in aggregated or anonymised form, under clear user consent and data-sharing rules.

Built on a federated architecture, the ODEON platform distributes intelligence across cloud, private servers, and edge nodes, embedding lightweight AI even in low-power devices. This local control is essential for real-time energy management, personalised optimisation, and secure operation in modern, distributed energy networks.

ODEON is developing innovative tools to help Local Energy Communities better manage flexibility and participate actively in energy markets. At the core of this effort is the community portfolio management and elasticity-based demand response tool developed by ETRA.

The tool enables operators to monitor distributed assets such as solar panels, batteries, and electric vehicles, anticipate user behaviour, and optimise energy flows in real time. Powered by ODEON’s cloud-edge platform and supported by secure data sharing, it helps reduce imbalances and improve coordination across decentralised systems.

The first HEDGE-IoT Open Call officially closed on 24 October 2025, attracting an outstanding 147 applications from 30 Horizon Europe–associated countries. This strong response reflects the growing interest among innovative SMEs and startups in developing IoT-enabled, data-driven energy services.

Through HEDGE-IoT’s cascade-funding mechanism, up to 12 selected applicants will receive financial and technical support—up to €60,000 per project, with a total of €700,000 available—to create and validate cutting-edge digital energy solutions aligned with the project’s European pilot sites.

The evaluation process is underway, assessing proposals on Excellence, Impact, Technical Quality, and Feasibility. Successful applicants will soon join the HEDGE-IoT ecosystem, contributing fresh innovation to Europe’s energy transition.

The TwinEU consortium (Horizon Europe project) is entering its final year. This critical phase will focus on live demonstrations of its use cases and pan-European scenarios, moving closer to a federated Digital Twin (DT) framework for Europe’s electricity grid.

The project aims to create a pan-European DT by federating local twins, enabling reliable, resilient, and safe grid operation while accelerating renewable energy deployment.

TwinEU tackles the challenge of coordinating energy systems through interoperable Digital Twins, secure data and model exchanges, and standardised interfaces that allow external actors to connect seamlessly. This federated approach ensures system operators retain independent control while contributing to a unified digital replica of Europe’s energy infrastructure.

In 2026, eight demonstrators across 11 EU countries will showcase how interoperable Digital Twins enhance cyber-physical grid resilience, support grid management and optimisation, and enable smart, coordinated planning. These demonstrations will validate TwinEU’s reference architecture, proving it is scalable and replicable across Europe’s diverse energy systems.

The WILSON Horizon Europe project successfully held its Mid-Term Meeting on 10–11 December 2025 in Grenoble, France, hosted by CSTB (Centre Scientifique et Technique du Bâtiment).
